Sorry for the slow response, I've been trying to catch up on things around the house and at work.
As soon as I get the next Borahgami finished I can get those measurements for you, let me know what configuration you would like me to measure.
Right now when the tarp is laid flat it measures 8' x 7 1/2', this would be just the portion of the tarp without the wings, minimum peak height was 34" set up in storm mode, but that can be adjusted with how high you want to set the tarp off the ground, so if you rasied it 3-4" that would change the peak height to around 37-38"
If you use the tie outs on the wings in storm mode that will get you about another 6" at each end.
The tie outs are located at the 90* point where the door would close (at the top were the ridge line is at)a tie out on each wing tip and a tie out between the wing tip and the corner tie out, one at each corner of the tarp as it is in storm mode, and then one on each side in the middle along the bottom, plus 2 pull outs one on each side that are in the middle of each pannel, these are put on with silicone adhesive then the tie outs are sewed on to those.
The material used is silnylon 30D from Noah Lamports
I hope this answers some of your questions.
12 tie outs total around the perimeter with 2 pull outs one on each side.
